Abstract
The utility model discloses a feeding mechanism of a feeding type screening machine. At present, a plurality of feeding rollers in a feeding section move consecutively and evenly, but due to the fact that materials in the feeding section are large in size and heavy in weight, the final speed of the materials can not be the same as the speed of a screening section roller. Consequently, the screening roller increases friction with the materials in order to drive the materials, abrasion of the screening section roller is increased, and the service life of the roller is short. The feeding mechanism comprises a plurality of feeding rollers which are arranged in parallel and a power device driving the feeding rollers to rotate. The feeding rollers are connected with one another through speed changing transmission devices, so that the feeding rollers are made to gradually accelerate along the feeding direction. Feeding rollers close to the inlet end are low in speed, and after lagging behind the feeding rollers, the materials gradually accelerate along with the feeding rollers, so that the friction between the materials and the feeding rollers is reduced. After the materials accelerate, the speed of the materials is close to the speed of screening section rollers, so that the friction of the screening section rollers is reduced, and the service life of the screening machine is prolonged.
